PDU138 Description
The PDU138-series device is a 3-bit digitally programmable delay line. The delay, TDA, from the input pin (IN) to the output pin (OUT) depends on the address code (A2-A0) according to the following formula: TDA = TD0 + TINC A PIN DESCRIPTIONS IN OUT A2 A1 A0 EN/ VCC GND Delay Line Input Non-inverted Output Address Bit 2 Address Bit 1 Address Bit 0 Output Enable +5 Volts Ground where A is the address code, TINC is...
